I like how the Lego T. Rex has feathers on his arms and no where else but the computer animated one doesn't have any at all, lol.

The stegosaurus sounded like Peter Griffin then.

Oh wow, I would've loved this as a kid if I'd seen this commercial... These dinosaurs are pretty much prototypes. I had the Dinosaur sets from 2001, but I never knew this existed... I recognize the green T-Rex from the ending scene in Lego Studios Backlot and never knew it came from actual Lego sets.

Lol at Sam Sinister being eaten by a T Rex. Karma got into him

I used to have this Lego set as a kid.  I miss it so much!

I REMEMBER THIS COMMERCIAL FROM WHEN I WAS A LITTLE KID

I have Sam Sinister catching the T-rex cub. I found another t-rex cub at a charity shop.

A HA! I FINALLY FOUND THIS COMMERCIAL!

Has anyone seen this on Fox Kids, Kids' WB!, Disney's One Saturday Morning, Cartoon Network, or Nickelodeon?

I still have the sets shown in this ad, still in tact along with the manuals, and I even still have some of the boxes.

Funny dinosaurs!

Before minecraft

Sweet!

Cool

Using computer-animated actual dinosaurs technically does not fit in a lego ad.
